Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
26 ms ... rise ↗ and fall ↘ combined	↗ 5 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 21 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 61 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.3 ms).
↔ Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined	↗ 15 ms rise
39 ms ... rise ↗ and fall ↘ combined	↘ 24 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 58 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (31.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8167 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Dell Latitude 14 E5470. Test model courtesy of Notebooksbilliger.de

戴尔为我们带来了一台具备优秀性能的高品质商务笔记本电脑。尽管Latitude 14 E5470搭配了较老的Skylake处理器，不过最新的Kaby Lake处理器也会在某些情况下处于劣势。四颗物理核心在支持多线程的程序中会更高效。强劲的处理器搭配8GB内存和256GB固态硬盘保证了流畅的系统运行。

戴尔的Latitude 14 E5470凭借测试中的优秀系统性能让我们十分满意。它的输入设备，坚固美观的机身和高品质工艺都可以保证较长的使用寿命。完备的安全功能和实用的配件也可以让办公更佳便捷。

戴尔的Latitude 14 E5470并没有让我们有很多可以挑剔的地方，不过我们还是希望它至少可以提供一个USB-C第二代接口，保证与未来设备的兼容。它屏幕面板的选择十分成功，不过在这个价位上它的对比度还是相对较低。

不过我们仍然可以为需要一台每日商务办公设备的用户由衷推荐戴尔Latitude 14 E5470。它完备的安全功能带来了加分，可能会成为是否值得选择的关键因素。
